IMPRovnD DUMPING-CAR The Schedule referred to in these Letters Patent` and making part of the same.

To all 'whom it may concern Be it known that I, CLINTON H. SAGE, of Fulton, in the county of Oswego, and `State of New York, have invented an Improved Revolving Dumping-Car; and I do hereby declare that the following is Ya full and yexact description thereof, reference being had to the accompanying drawings, making part of this specication Figure 1 being a front elevation of the car;

' Figure 2, a side elevation thereof;

Figure 3, a plan of the truck, the car-bodies and frame being removed;

Figures 4, 5, and 6, views of parts detached.

Like letters designate corresponding parts in all of the figures.

In the construction of this car an ordinary truck or plattbrm-car, T, may be used, of the required gauge.

The platform S thereof is made of sutheient size to receive, between the wheels t t, an annular or circular track, A, which is securedceutrally thereon, as represented.

Thusthebody of the car, which is to revolve upon this track, can be brought low enough to easily till with shovels.

I allow a b eam or "timber, r, to project from the truck-flame at each end, for the car-bodies or boxes to strike aud rest on in dumping, and limit the extent to which they tip. p

These timbers may serve .to couple anddraw the cars by.

Similar beams or timbers, s s, project at the sides,

.for dumping at the sides of the track.

Upon the track A, a frame, B, rests, being provided with four frictionwheels, C C C C, situated within in tig. 3.

'lhe ends of the axles D D rest iu boxes E E,

4'shown separately in iig. i, which are' secured by tlanehesand bolts in the corners of the frame.

These strong angle-irons or boxes sustain the whole weight of the load.

The friction-wheels C (l have conical faces, they being parts of cones whose yapexes coincide with the centre ot' the annular track on which the wheels travel; and inorder that thcwhcle face or tread of these wheels may rest Aand roll upon the track, the journals of the axles D D, on which thewheels turn, are inclined, as shown in tig. 4, just sutiicient to bring the lower line, or line of contact between the wheels and track, on a level.

Thus the wheels run with as much freedom and with as little friction as cylindrical wheels on a straight track.

The axles D D cross each vother over the centre of' They are pivoted to the outer ends of the frame,

and, under their own centres, on axes or journals L L, so as to be tilted and dumped, as seenat the right hand in iig. 1.

The relative dimensions of the boxes and frame are such that the boxes will benearly or exactly balanced thereon, so as to tilt easily with their loads, and the whole frame balanced by the twoboxes.

Thus the whole iame B can be turned to any posi- -tion with the carfbodies or boxes, and dump the loads either at the ends or. sides of the truck, or both bodies successively at one end or one side.

When the two boxes are loaded, whatever their position on the tru'cln'they are balanced.

The doors or tail-boards M M of the car-boxes are self-opening, as the boxes are tilted and dumped, by means of a device substantially as follows:

At the sides of thc frame I5 projecting timbers G G are secured, for the purpose of support-ing fixed oblique standards H H, substantially as represented in tig. l.

These standards are so arranged as to support, in grooves, or notches, or brackets, at their upper ends, or otherwise, the upper sides of angle or brace-irons K K, to which the doors or tail-boards are aiiixed.

l'Ihe inner ends of the angle-irons are pivotcd, at 7c lr, to the car-bodies or boxes.

The wholcarrangenient is such that as the boxes are tilted, thedoors or tail-boards are held suspended or raised away from the open ends of the boxes, leaving the saine free to discharge their contents, all as clearly indicated in the same figure.

The doors are entirely automatic in action, and require no attention.

The car-bodies or boxes are held upright by catches an in., figs. 1 and 5, working under loops n nl, or their equivalent.

The brakes of the car-wheels are operated at the centre of the car.

The central pivot-shaft I is situatedin this position, and serves the purpose of winding the brake-chains on, a brake-wheel, p, being secured to its upper end.

y Thus the brakes are applied with equal eliicacy and ease, whatever' the position 'of the car on the truck;

nor does it interfere with the motions of the car-bodiesA or boxes in any position.

What I claim as my invention, and desire to secure 1. The combined construction and arrangement of the revolving balanced frame B, covering and shield ing the curved track A, on the car-truck, and the two counterbalancing'car-boxes F F, substantially as herein specified.

2. Also, the'inclined journals ou the'axles D D, arranged, in relation to the conical friction-wheels C C and level track A, substantially as and forthe purpose specified.

3, Also, the xed supporting-standards H H, arranged in combination with the carboxes F F and brace-irons K K, on which the tail-boards M M are mounted, so as to raise said tail-boards as the oarfortli.

y 4. Also, the employment of the pivot-shaft I, around which the car-'frame B turns, for the additional purpose of a brake-rod or shaft, as specified.
